Embodiment 1
[0029] Preparation of 500g one-component acrylic resin marine antifouling coatings containing capsaicin derivatives: weigh the components as follows: 250g acrylic resins containing eugenol capsaicin derivatives, 25g iron oxide red, 25g BYK-P104, 10g Fumed silica, 30g combined antifouling agent, 60g xylene, 100g butyl acetate.
[0030] Preparation process: fully disperse 10g of fumed silica, 25g of iron oxide red, and 25g of BYK-P104 on a high-speed coating disperser (1500 / min) for no less than 30min, and grind until the particle size is less than 50μm to obtain a solid mixture; The ground solid dispersion was added to the mixed liquid containing eugenol capsaicin derivative acrylic resin 250g, combined antifouling agent 30g (A component 6g, B component 24g), xylene 30g and butyl acetate 50g, and then Stir the mixture evenly under high-shear (1500 / min) stirring, and add the remaining xylene and 80 g of butyl acetate at the same time to adjust the viscosity to 60 s.
Embodiment 2
[0032] Preparation of 1kg single-component acrylic resin marine antifouling paint containing capsaicin derivatives: weigh the components as follows: 400g acrylic resin containing eugenol capsaicin derivatives, 100g iron oxide red, 50g zeolite, 50g BYK- 163. 80g combined antifouling agent, 170g n-butanol, 150g butyl acetate.
[0033] Preparation process: fully disperse 50g of zeolite, 100g of iron oxide red, and 50g of BYK-163 on a high-speed paint disperser (1500 / min) for no less than 30min, and grind until the particle size is less than 50μm to obtain a solid mixture; grind the above-mentioned The solid dispersion was added to the mixed liquid containing eugenol capsaicin derivative acrylic resin 400g, combined antifouling agent 80g (A component 8g, B component 72g), n-butanol 100g and butyl acetate 50g, and then the mixture Stir evenly under high-shear (1500 / min) stirring, and add the remaining n-butanol and 170g of butyl acetate at the same time, and adjust the viscosity to...
Embodiment 3
[0035] The preparation of the one-component capsaicin derivative acrylic resin marine antifouling coating of 1kg: each component is weighed as follows by formula: 400g contains eugenol capsaicin derivative acrylic resin, 50g iron oxide red, 50g zinc oxide, 50g flow Leveling agent 3033, 80g combined antifouling agent, 170g n-butanol, 200g butyl acetate.
[0036] Preparation process: fully disperse 50g of zinc oxide, 50g of iron oxide red, and 50g of leveling agent 3033 on a high-speed coating disperser (1500 / min) for no less than 30 minutes, and grind until the particle size is less than 50 μm to obtain a solid mixture; grind the above Add the processed solid dispersion into the mixed liquid containing eugenol capsaicin derivative acrylic resin 400g, combined antifouling agent 80g, (A component 20g, B component 60g) n-butanol 60g and butyl acetate 100g, and then Stir the mixture evenly under high-shear (1500 / min) stirring, and add the remaining n-butanol and 210 g of butyl acetat...
